Minecraft

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 4090 delivers a striking performance profile in Minecraft, one that flips the usual bottleneck expectations. The data shows a system that is overwhelmingly GPU-bound at higher settings and resolutions, yet CPU-bound at the lighter load extremes where the RTX 4090’s raw power is held in check by the processor’s six Zen 2 cores.

Resolution Scaling

The frame rate drop from 1080p to 4K is the single most revealing metric for this combo. At 1080p High settings, the average is 421 FPS. At 1440p High, it climbs to 357 FPS, and at 4K High it falls to 187 FPS. The scaling pattern between 1080p and 1440p is remarkably flat—a drop of only 15.2%—which signals that neither component is fully saturated at these resolutions; the engine is likely behaving in a way that keeps the CPU threads busy while the GPU still has headroom.

The true bottleneck appears when pushing to 4K. Moving from 1440p High (357 FPS) to 4K High (187 FPS) is a 47.6% reduction, a far steeper drop than the pixel count alone (2.25×) would predict, but not a linear one either. This indicates that at 4K, the RTX 4090’s raw compute—its 82.58 TFLOPS FP32 and 1.01 TB/s memory bandwidth—is finally becoming the primary limiter, though the CPU still contributes some overhead.

The Low settings curve is even more informative. At 1080p Low, the average is 498 FPS. At 1440p Low, it’s 427 FPS (a 14.3% drop), and at 4K Low it’s 297 (a 30.4% drop from 1440p). The fact that 1080p Low and 4K Low differ by 40.4% suggests that even a massive 24 GB GDDR6X buffer and 1.01 TB/s bandwidth can’t eliminate the resolution penalty entirely, but the numbers also show that the CPU is the primary limiter at 1080p Low: the 4600G’s single-thread score of 726 in 3DMark and 1919 in Cinebench R23 single-core are simply not enough to push the 4090 past 500 FPS in a heavily single-threaded game like Minecraft.

The Ultra settings reveal the most dramatic scaling cliff. From 1080p Ultra (351 FPS) to 1440p Ultra (223 FPS) is a 36.5% drop, and from 1440p Ultra to 4K Ultra (117 FPS) is a 47.5% drop. This is a classic GPU-bound curve: the RTX 4090’s pixel rate of 443.5 GPixel/s is being pushed to its limits at 4K Ultra, and the 117 FPS result is still respectable but demonstrates that Minecraft’s rendering paths can stress even the flagship Ada Lovelace part.

CPU Role

The Ryzen 5 4600G is a 6-core, 12-thread Zen 2 part, based on the Renoir die on a 7 nm process. It boosts to 4.20 GHz and has a 65W TDP, with 8 MB of shared L3 cache. In Minecraft, the data shows that the CPU is rarely the primary constraint except at the lowest GPU loads. At 4K Ultra, where the GPU is the bottleneck, the CPU’s 12 threads are likely not fully engaged—the game is not heavily multi-threaded in its core rendering path, and the 4600G’s multi-threaded scores (Cinebench R23 multicore of 13593) are sufficient to avoid being the main limiter.

However, at 1080p Low, the CPU’s single-thread performance becomes the ceiling. The 4600G’s Passmark single-thread score of 2653 and 3dmark_single_thread score of 726 are modest by modern standards, and the game’s main thread is often the bottleneck in such a scenario. The 1080p Low average of 498 FPS is 12% lower than the 1440p Low average of 427 FPS, but the 4K Low average of 297 FPS is 30% lower than 1440p Low. This pattern—where 1080p and 1440p are relatively close, but 4K is much lower—indicates that at 1080p Low the CPU is limiting, and at 4K Low the GPU is limiting, but at 1440p Low both are partially saturated.

The CPU’s L3 cache of 8 MB is modest, but Minecraft’s world data typically does not require massive cache capacity; the game’s performance is more dependent on single-threaded instruction throughput and memory latency. The 4600G’s dual-channel DDR4 memory support with 51.2 GB/s bandwidth is not a known constraint in the data, but the CPU’s PCIe Gen 3 interface (20 lanes) is sufficient for the RTX 4090, which is a PCIe 4.0 x16 card but can run on Gen 3 with minimal performance loss in most games.

GPU Role

The NVIDIA GeForce RTX 4090 is the centerpiece here, with 24 GB of GDDR6X memory on a 384-bit bus, delivering 1.01 TB/s of bandwidth. Its 16,384 shading units, 512 TMUs, and 176 ROPs, along with 128 RT cores and 512 Tensor cores, provide the raw power that dominates at high resolutions. The boost clock of 2520 MHz and base of 2235 MHz are high for a GPU of this size, and the 82.58 TFLOPS FP32 performance is the reason that 4K High is still playable at 187 FPS.

The GPU’s role in Minecraft appears to be mostly about fill rate and memory bandwidth for large draw distances and complex scene geometry. At 4K Ultra, the average of 117 FPS is a 37.5% drop from 4K High (187 FPS), which shows that the Ultra settings (likely shadows, anti-aliasing, and render distance) are heavily GPU-intensive. The GPU’s 443.5 GPixel/s pixel rate is a likely factor in this, as higher pixel fill requirements directly impact frame times.

The GPU’s 3DMark Steel Nomad DX12 score of 9223 and Passmark G3D of 38194 are consistent with a top-tier part, but its nearest rivals in the benchmark data are not consumer gaming GPUs—they are professional parts like the Intel Arc Pro A60 (avg score 60326, delta 0%) and AMD Radeon Pro W6600M (avg score 61896, delta -2.5%). This suggests that the benchmark’s synthetic scores are less relevant to Minecraft than the measured FPS, which is the true indicator of real-world performance. The GPU’s 88th percentile among all GPUs is a summary of its synthetic power, but the Minecraft results show that even a 4090 is bottlenecked by the CPU in certain scenarios.

Measured FPS Breakdown

The full FPS table is as follows:

• 1920x1080 Low: 498 FPS average
• 1920x1080 Medium: 458 FPS average (min 389, max 526)
• 1920x1080 High: 421 FPS average
• 1920x1080 Ultra: 351 FPS average

• 2560x1440 Low: 427 FPS average
• 2560x1440 Medium: 393 FPS average (min 334, max 452)
• 2560x1440 High: 357 FPS average
• 2560x1440 Ultra: 223 FPS average

• 3840x2160 Low: 297 FPS average
• 3840x2160 Medium: 235 FPS average (min 200, max 270)
• 3840x2160 High: 187 FPS average
• 3840x2160 Ultra: 117 FPS average

The Medium settings show the most consistent frame pacing, with the 1080p min of 389 FPS and max of 526 FPS suggesting a ~35% variance, which is typical for Minecraft’s chunk loading and entity updates. The 4K Medium has a min of 200 FPS and max of 270 FPS, a tighter range that indicates the GPU is more stable at 4K than at 1080p, where CPU spikes can cause more variance.

At 4K Ultra, the min FPS is not recorded in the dataset, but the average of 117 FPS is still above the 60 FPS threshold for smooth gameplay, even with the most demanding settings. The 1080p Ultra average of 351 FPS is surprisingly high, only 16.7% lower than High, which suggests that the Ultra settings at 1080p are still not fully stressing the GPU, leaving headroom. The 1440p Ultra average of 223 FPS is a 42% drop from the 1440p High average of 357, which is exactly the kind of performance cliff that Ultra settings impose.

How This Combo Ranks

This AMD Ryzen 5 4600G + NVIDIA GeForce RTX 4090 combo ranks #541 out of 3,710 tested combos in Minecraft, which places it in the top 14.6% of all combinations. That is a surprisingly low rank for a GPU that is the fastest consumer card, but the explanation is the CPU. The 4600G is a modest 6-core part, and in a game like Minecraft that is heavily single-threaded, the CPU’s single-thread performance (PassMark single-thread 2653, 3dmark single-thread 726) is a significant drag.

The CPU’s percentileVsAllCpus is 71, meaning it is better than about 71% of all CPUs, but its nearest rivals in synthetic benchmarks are all low-power parts: the AMD Ryzen 3 PRO 5355GE (avg score 17482, delta 0.1%), the AMD Ryzen 3 8300GE (avg score 17614, delta -0.6%), and the Intel Core i3-14100T (avg score 17648, delta -0.8%). These are all low-power, low-clocked parts, and the 4600G is in their company, not in the category of high-end gaming CPUs.

The GPU is in the 88th percentile, but its nearest rivals in the database are not gaming parts, which is a reminder that the GPU is a professional workhorse. The rank of 541 out of 3710 means that many other combos, likely with better CPUs, outperform this one in Minecraft despite having weaker GPUs. The data indicates that a lower-tier GPU with a high-IPC CPU would likely produce a higher rank in this game, because Minecraft’s frame rate is more responsive to CPU single-thread speed than to GPU fill rate.

FAQ

Q: Does the RTX 4090’s 24 GB VRAM help in Minecraft?

A: The 24 GB of GDDR6X with 1.01 TB/s bandwidth is not a limiting factor in this game. The measured FPS at 4K Ultra is 117 FPS, which indicates that the GPU’s compute is the limiting factor, not its memory capacity. Minecraft’s texture sizes and render distances do not require 24 GB of VRAM, so the 4090’s memory size is irrelevant for this title; its raw compute (82.58 TFLOPS) is more relevant.

Q: Why does the 1080p Low average of 498 FPS not increase to 500+?

A:** The CPU is the limiting factor at 1080p Low. The Ryzen 5 4600G’s single-thread score of 2653 in PassMark and 726 in 3dmark_single_thread is not high enough to drive the 4090 beyond this frame rate. The GPU has headroom, but the CPU’s main thread cannot issue enough draw calls.

Q: Is the 4600G a good match for the RTX 4090?

A:** No, the data shows a significant bottleneck. The combo ranks 541st out of 3710 in Minecraft, which is below average for a system with a top-tier GPU. The CPU’s 71st percentile and the GPU’s 88th percentile indicate that the CPU is the weaker component, and the game is CPU-bound at low settings and resolutions.

Q: How does the 4K Ultra performance of 117 FPS compare to 1440p Ultra (223 FPS)?

A:** The 4K Ultra is 47.5% slower than 1440p Ultra. This is a classic GPU-bound scaling because the RTX 4090’s pixel rate and shader resources are taxed heavily at 4K. The CPU is less of a factor at 4K, but the GPU’s 82.58 TFLOPS is still not enough to maintain 1440p-level frame rates at the higher resolution.

Q: What is the frame time consistency at 1080p Medium?

A:** The 1080p Medium setting shows a min FPS of 389 and a max of 526, with an average of 458. The wide range indicates that the CPU causes stuttering during chunk loading, as the 4600G’s 12 threads and 8 MB L3 are not fully effective at smoothing these spikes. The 4K Medium range is 200-270, which is a narrower, indicating more stable GPU-bound performance.

Q: Is this combo a good choice for 4K gaming?

A:** For Minecraft specifically, the 4K High average of 187 FPS is excellent, and 4K Ultra at 117 FPS is still smooth. However, the combo’s rank of 541 out of 3710 suggests that there are many better combinations for this game, and that the RTX 4090 is overqualified for the CPU. A more balanced CPU would likely yield a higher rank.
